In order to follow up the PRRS situation in the farm, what type of serology test would you recommend besides ELISA and/or PCR? Is it realistic and accurate to test IFN gamma or IL-10 to show whether the management/ treatment is implemented properly?

Cytokines determination has been used to study PRRS infection under experimental conditions but it’s not a test routinely used, may be because of different reasons:

2. Abnormal levels in a PRRS infection are not yet well established. We do not know if there are differences between different strains, probably this is the case as some of these products (IL-12) have been related to persistence of the virus in the lung.

3. Some of these inflammatory products have a short life which is the case of IL-10 (in some experimental studies levels are reduced at 42 dpi).
